ZoneDirector v10 - service schedules off by an hour

Since the upgrade to v10, I have noticed that all of my service schedules are activating and deactivating one hour behind their scheduled times. Controller itself is syncing against NTP and displays the appropriate time. I have raised an issue with support but wanted to see if anyone else has come across this issue?

Case # 00539558 - It's quite possible that it is related to DST. I also had issues, however, disabling NTP and attempting to sync the controller time against my browser - ZD UI hung and never performed time change. I have temporarily settled on changing the time zone of my controller in order for service schedules to work appropriately while this is worked through. Thank you.
